FILM-PERFORATING MACHINE.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application led July 28, 1909. Serial No. 510,093.

City, in thecounty of Hudson and State of t' New Jersey, have inventedcertain new and y useful lmprovements inlidia-Performing Machines. ofwhich the following is a full,

clear, and exact specification.

My invention relates to machines for perforating sheets, and while itmay be used for a lvariety of purposes where such operations arerequired, it is designed with a view to use in perforating reinforcingstrips secured to photographic films such as are used in moving-picturemachines.

The object of the invention is to provide vmeans for manuallycontrolling the spacing between perforations, thereby insuringuniformity inthe position of the perforations and the registry of theperforations in such reinforcingr strips with the perforations in thefilm; also permittingl an uneven spacingY in` the original perforationto he corrected and to. enable such adjustment to he effected whilethemachine is in operation. 'lhese and other objects which will appea asthe description proceeds, I' accomplish hy the improved construction ofmachine hereinafter descrilied and illustrated in the accompanyingdrawings wherein-5 t Figure 1 is a front elevation of my improvedmachine. Fim-2 is an elevation taken fromthe left, aiidpartly insection, on

the line 2-2 of Fig'. l. Fig. 3 ,is a rear ele- A .vation; and Figi'. 4a plan view. l

': The long' films as usually supplied for inovinir.-picti.1-"mairliines arc perforated in use, and such reinl'oreements when appliedcover the pertorations in thc lilm. lt necessary, therefore, tolpcrl'orate such lhesc perforations must register exactly with the.pcrtorations ex isting in the film in eases where thel latter wascorrectly perforated, and should correct any uneven perforation in thelihn.

VMy invention is designed to form such perforations in the reinforcingstrips in exact register `with the previous pertoratlons where they areright, orto pcrtorate the .and standards 3 4.

tilm evenly where the'original perforations were uneven.

The main shaft of my machine runs from front to rear and the punches aresituated at what I designate as the front of the machine.

Upon a bed-plate l is mounted the :trame of the. machine, comprising abase-plate 2, The front standard 4 may, if desired, lie formed with astitlening weh 5. The upper ends of the standards are lprovided withbearings G, 7, for the main shaft 8. Upon this shaft is loosely mountedthe driving pulley 9, which is oper-- atively connected to the shaftthrough clutch wh'eels 10, 11, the first of which is fixed to the pulleyand the second keyed upon the shaft by key 12, so as to slid and iscontrolled by clutch-operating lever 13, fixed to the frame at 14. u

A film-carrying table 15 is supported at the front of the machine uponposts, ot' which 1G, 17, only are seen, but ot which there may beanysuitable nnmhcr.V The table is also supported hy a lnace 154, whichis holted to its receiving,l end on the. inneil side and is alsoattached to a box-like frame 19, which has rails 20, 2l, situated uieneach side ol the table and a stripper-plate 22 passing over the taldeand lilm and holding),A the latter in place when the punches rise.

At the lett: ofthe table a pair of revolving guide-rollers Q25, Q4, aresupported upon side-brackets 25, Qt, attached to the rails 20, 2l,sulliciently near together to guide the lilm '27 between them. As thelihn emerges from the guide-rollers, it, )asses along the tahle underthe stripper-plate and is held in close proximity to the tahle adjacentthe punchthy a flat-spring 28 (seen in section in ["ig'. 1') lormed outo'l' the stripper-plate hy slitting' the s:\ine,':iiid which has aspringpi'e.-:s|ue upon the upper surface ot' the tilm.

hardened die, inserted in the table, is perl'orattnl at 2S) (Fig. l), topermit the passage of the punches 30, of which there are two, one'oncach side of the film, as seen in Fis: 2. V The punches are adjustahlymount- .cdin'a head 3l, which iS attached to a slidpitman 3.3 connectsthe block' with a crankcentric cam 37 (Figf),

in 36, mounted eccentrically upon the end of the main-shaft 8, andturning 1n thenpy per bearing of the pitman, whereby the rotation of themain shaft is converted into a reci rocation of the punch. Tiie feedingdevice is actuated by an ecfixed upon the main shaft at the rear of themachine and which rocks the rocking-arm 38 of a rocking lever throughroller 39. This rocking-arm is fixed upon a rock-shaft'40, extendingfrom front to 'rear of the machine, and is retracted and operated by acoiled-spring 4l, attached at one end to the said arm and at the otherend to a bracket 42, projecting to the right of the machine from therearstandard 3. The motion of the rocking-lever is limited in one directionby the cam Y37, and in the other direction by a stop 43, which is upon alower extended branch ofthe rocking-arm and encounters the lower end ofan adjusting stopscrew 44, which is adjustable for a purpose presentlyto be described.

Upon the forward end of rock-shaft 40 are fixed rocking-arms 45, whichgive a reciprocating motion to film-feeding fingers 46,

' which are lloosely hinged upon an axle 47,

" finger.

. a perforation and are which has bearings 'on the rocking-arms 45.Attached tc each finger is a short bracket 48 extending inward and whichprovides an auxiliary bearing upon the axle 47 for'the The fingers 46are maintained in position to engage .the film by springs 49, mountedupon a rod 50, connecting the outer ends of the rocking-levers (Fig. 4)and these fingers at their free ends terinlnate in downwardly-extendinghooks 51, which are adapted to enter the perforations in the film formedby the punch and-have their outer ends beveled to ride freely out of theperfoV rations in their forward movements.

The operation of that the feeding fingers move forward toward the punchto engage a-fres'h part of the film when the punch is down, therebaviding an :liability that the fingers wil move the fi m the wrong way.'`When the punch rises the fingers are in position over forced down bytheArocking-lever is retracted,

springs and the art of the film'under the feeding a fresh punch.

It occasonally'ha pens that filmsare improperly perforate when made, andthis must be corrected. It also 'happens that films, from vagriouscauses, mayre uire to be perforated, o that perforatons o differentspacings--may be required. .loA enable this to be successfullyaccomplished, I have providedf my machine feedin mechanism,

,which I regardas` the `most important .feature of my invention.` ofthis adjustment the feeding;

By means fingers may be made to feed more or less fihn under the punchat each feeding movey ment, and

, imits the feeding movement of the feedlng device.

the machine is so timed Aof perforat-ons, upon a across the top of tuobrackets 65, which are with finely-adjustable thereby the space betweenerforations may be varied as desired This device is capable of fine andexact adjust-ment is maintained as long These results Iaccqm- 44 rwhichand the adjustmentas desired when lset.

lish by the threaded stop-screw feeding-' fin ers Fig. 3);This-stop-screw takes into I aft rea ed bearing 52, carried upon a rec--tangular bracket 53, 54, which is supported u on posts 55 56, fixed tothe base-plate 2'.

e stop-screw 44 carries a locking-wheel 57, formed 4With a series oflocking, serrated teeth 58 upon its upper face near the perimeter, andthese teethare engaged by a lock mg 60, carried by a brace ar 61, whichat its front end is attached to the under side of the table and at itsrear end is attached to apost 62 upon arm .53, situated underlocking-wheel 57.

A spring (33 is coiled abouta stop-screw 44, and presses at and at theother end against the whee and serves to take up any lost motion in thethreadof the stop-screw. It will be perceived that the rocking-arm 38,shaft 40, and

rocking arm 45 constitute a rocking-lever, by which, in connection withthe cam 37, the rotary motion 'of the shaft is converted into ahorizontally-reciprocating motion of the feeding-hooks and that thelength of this motion 1n the feeding direction is Varied as thestop-screw is raised or lowered.

J The pitch of the screw 44, and also the lserrated locking-teeth 58 maybe made as fine as desired, and the finer these parts are, the renterthe extent of adjustment for the Means are also provided for clearingthe erforations b v removing any bur or punchlugs from the perfor-ationsthat lhave not been entiely removed fronrthe film. A burrenioving deviceis shown atI the right of the machine. and in the illustration comprisesa pair of spring-fingers 63a. one for each row bar 64, extendingattached to the table.- Thesefingers have their ends bentv downforentering the perforations, and tend to push out any adhering punchings.'lhe fingers in their clearing acton are shown coperating with movingmembers. A serrated roller 66 is shown below each finger 63. The rollers66 are fixed upon a revolving in an arm 68, lnouuted upon a post 70 andarm 59. which ispjvoted" upon a post.
